QUEBEC: Quebec Hydroelectric Power System

This set of matrices if from the application of the Hydro-Quebec power systems' small-signal model. In the application, one wants to compute all eigenvalues a + b i in a box of the complex plane. Specifically, amin &lt a &lt amax and, in general, amin = -300 and amax = 300. bmin &lt b &lt bmax, and, in general, bmin = 0 and bmax = . Note that the matrices are highly unbalanced.
